11 Conceptual Locations General concept location criteriaUndeveloped landRelatively flatRelatively close to waterway or floodplainRelative location to geologic formationIndividual concepts have unique considerationsPreferred project locations to be confirmed during Feasibility Phase based on additional criteria

12 Recharge CriteriaWilson Grove and Petaluma Formations are most effective for water supply rechargeAlluvium above Wilson Grove and Petaluma also considered viable for water supply rechargeOther alluvium could provide benefits other than water supply recharge

20 Concept 8: Bridge Improvement and Debris RemovalGoal: Improvement of bridge areas to reduce potential for flooding due to debris build-upConcept could lead to less emergency operations and maintenance

22 Concept 10: Policy Review and DevelopmentGoal: Identify policies that impact flood hazards and groundwater recharge and update as necessaryCollaborative concept could be applied at local or county-wide scales.

23 Concept 11: Direct RechargeGoal: Pump water directly into aquifersBetter control of water quality entering aquifers than percolation methods
